Extraterrestrial Sed/Strat: Constraining the Evolution of a Delta Deposit on Mars using Remote Sensing

Decades of planetary exploration have revealed widespread evidence for ancient fluvial activity on the surface of Mars, including deeply incised valleys, paleolake basins, and an extensive fluvial sedimentary rock record. Acquisition of high-resolution remote sensing data of the martian surface (e.g., images and topography) over the past 5-10 years have allowed for quantitative analysis of the large-scale sedimentary structures of martian fluvial deposits. In this talk, I will focus on a detailed study of the stratigraphic architecture and channel deposit geometries of the Jezero crater delta deposit on Mars. Results from this study are used to develop a self-consistent stratigraphic framework for the deposit, and reconstruct a scenario for the evolution of the Jezero crater delta and paleolake in which it formed. This delta deposit is a representative example of ancient fluvial stratigraphy on Mars, and these results can help to improve our understanding of ancient martian fluvial activity. Jezero crater is also of particular interest, as it is one of three sites undergoing further consideration as the landing site for the next NASA rover, the Mars 2020 mission
